Steady state stresses induced in a transversely isotropic elastic solid by a moving dislocation
This paper is concerned with the problem of a dislocation moving at constant speed in an unbounded, transversely isotropic elastic body. The connection between transient and steady state moving dislocation problems is studied. The author considers a previously obtained transient solution to the problem and, by means of an appropriate coordinate transformation, derives the steady state solution. The solution for the plane stress field is explicit and valid for dislocation speeds which are subsonic, transonic or supersonic with respect to the material wave speeds. The transient stress field caused by the moving dislocation is presented in a form which is suitable for the moving coordinate transformation and its subsequent time limit.
